Hemp lime wall elements with integrated formwork

Abstract

Modular hemp lime wall elements which are provided with an integrated formwork for concrete filling as a supporting structure, characterized in that the hemp lime wall elements (1) are mortarless and modularly connectable (2).

Description

[0001] Buildings of conventional construction consist of: Solid construction Materials: Concrete, reinforced concrete, masonry (natural stone, sand-lime brick, brick) Features: The supporting structure is usually made of solid building material, offering good fire resistance, often high sound insulation, and resulting in heavy building structures. Advantages: High durability, good sound insulation depending on the material, long service life. Disadvantages: Heavyweight, tends to have long construction times, thermal insulation is highly dependent on the material used; poor environmental impact potential.

[0002] Reinforced concrete or steel construction Materials: Reinforced concrete (reinforcement + concrete), reinforced concrete cores, frame components. Features: High load-bearing capacity, large spans, versatile adaptability. Advantages: High strength, flexible design, good fire safety. Disadvantages: Weight, corrosion and thermal insulation aspects, manufacturing costs, long construction times, poor environmental impact potential.

[0003] Timber construction (timber high-rise construction) Materials: Load-bearing structures made of wood, glulam, wood panels (CLT / BSP), Features: Lightweight structure, good thermal insulation, natural building materials. Advantages: Fast construction, lower building weights, good environmental balance potential. Disadvantages: High fire protection / fire safety requirements, fire protection regulations affect height restrictions, availability, sound insulation requirements, limited ceiling spans, complex construction due to multi-layered wall structure; increased planning effort.

[0004] Hybrid construction Features: Combination of wooden elements, concrete and / or steel, integrated depending on the functional part. Advantages: Combining the advantages of several systems (focus on sustainability, speed, load-bearing capacity). Disadvantages: High planning effort and complex construction due to different construction methods, coordination-intensive.

[0005] The invention described in the claim is based on the problem of compensating for the disadvantages of conventionally constructed buildings, combining the advantages in one product and improving it through new advantages.

[0006] The problem is solved with the features listed in claim 1-4 as follows.

[0007] The high degree of prefabrication of the mortarless, modular hemp-lime wall elements enables fast and efficient construction. The low weight of hemp-lime allows for easy assembly and transport.

[0008] The hemp-lime wall elements form the non-load-bearing exterior and interior walls. This single-material, monolithic building material enables fast, compact, and simple construction with short construction times, low planning effort, and individual design possibilities, as the system is not bound to a grid.

[0009] The modular hemp-lime wall elements simultaneously serve as formwork for concrete infill, ensuring a strong, high-strength connection with good fire resistance and reduced assembly effort. The complex and costly process of stripping and re-forming the reinforced concrete columns and beams is eliminated.

[0010] Hemplime, a natural building material, is easy to produce, dimensionally stable, CO2-negative, 100% recyclable, organic, durable, healthy for living spaces, and energy-efficient. Hemplime possesses excellent biophysical properties.

[0011] An embodiment of the invention is described with reference to the Fig. 1-3 explained. They show: Fig. 01 Assembly of the hemp-lime wall elements Fig. 02 View, top view and side view of a hemp lime wall element Fig. 03 Detailed connections

[0012] In Fig. Figure 1 shows how the hemp-lime wall elements are inserted into the steel reinforcement from above and cast in concrete. Fig. Section 02 shows different profiles for a mortarless plug connection. Fig. Figure 3 shows three detailed connections of the hemp-lime wall elements with different ceiling designs. From left to right: - Hemp lime wall element with embedded reinforced concrete beam as support for cast or precast ceilings - Hemp lime wall element with flush-mounted beam as a support for e.g. filigree ceilings - Hemp lime wall element with embedded reinforced concrete beam as support for a wooden ceiling Reference symbol list 1 hemp-lime wall element, 7.5 cm to 50 cm thick 2 plug-in profiles (different profile variants) 3 Integrated formwork, formwork tube d= 15-35cm 4. Concrete filling 5. Formwork concrete slab, precast or filigree concrete slab, glulam 6 possible cutouts for windows, doors, openings of various sizes 7. Reinforcing steel 8 Plaster base / facade cladding
